摘要
研究Beddington-DeAngelis发生率下具有感染时滞的HIV模型,通过考虑感染时滞对已有的模型进行修正;利用时滞微分方程的稳定性理论主要研究感染平衡点的稳定性和Hopf分支,通过数值模拟验证所得结论.
In this paper,an infection delayed HIV model with Beddington-DeAngelis infection rate is investigated. Firstly,by considering the infection delay,the existing model is corrected.Then,by the stability theory of delayed differential equation,the stability and Hopf bifurcation for the positive equilibrium are mainly analyzed. Finally,the numerical simulations are carried out to explain our theorems.
